Four Reasons Why Allergies Affect Your Whole Head


With hay fever season right around the corner and summer allergies almost done, you may be groaning internally about the unpleasantness of hay fever. Why does it have to affect your whole head? Here are four reasons why seasonal hay fever affects your whole head.

Numerous Internal Sinus Cavities and Their Connections

Your sinuses are not limited to your nasal passages. You have sinus cavities behind the upper part of your nose, above your eyes, and in your skull in front of your ears. When you have a histamine reaction such as hay fever, all of these sinuses begin to swell in order to block the allergens from entering your body. That is why you feel it in your cheeks, around your eyes and in your nose. (These cavities also allow for the free exchange of fluids in your head; tears run into your nose and throat to cleanse and mucous and ear wax runs down the back of your throat.)

Why You Tear Up

Along with the swelling of your sinuses, your eyes may tear up with hay fever. Because it is the job of your tears to flush out things that may be harmful to your eyes and to your bloodstream, your body is reacting to the allergens as though they were something quite harmful in the only way eyes know how to react--tearing or crying. Until your body has determined that it has successfully flushed the allergens from your eyes and the rest of your body, your eyes will continue to produce a lot of tears.

Why Your Nose Runs (Even with Swollen Nasal Passages)

Runny noses are par for the course with hay fever, but it does not quite explain why this happens when you are already so stuffed up and your nasal passages are so swollen. Much like the eyes and the eyes' attempt to flush the allergens from the body, your mucous membranes in your nose are trying to do the same thing. They create lots of extra mucous combined with tears (because your tear ducts are connected to your throat and nose!), and then your nose runs until the allergens are no longer detected.

Why Your Throat Feels Scratchy

Your throat is the gateway between your mouth and nose and your stomach and lungs. When you breathe, the air travels down the back of your throat, through the trachea and into your lungs. If allergens make it past your nose, it is only temporary because your sensitive throat will detect them. Once your throat becomes itchy, it has already activated the body's defense systems, and the histamine reaction begins. The scratchy throat feeling you have is the initial warning alarm to the rest of the body to get ready for battle.

Learning More About ENT Specialist Care Practices

Hello, welcome to my site. I am Ritchie. I am here to discuss ENT specialist care practices with you all. When I developed a constant ringing in one ear that progressed to partial deafness, I was referred to an ENT for an evaluation. The diagnostic process revealed damage in my ear that was repairable with surgery. The ENT performed the surgical repairs and guided me through the recovery process. I would like to use this site to explore other medical conditions that ENT specialists can diagnose and treat. I will also talk about the surgical treatments used for certain medical conditions affecting the ear, nose or throat.
